WWII Begins

World War II Began on 1 SEP 1939, when Hitler invaded Poland. His thinking was that he could get away with it, given the allies' string of appeasements in the face of his previous acts of aggression. He was wrong. On 3 SEP 1939, Britain and France declared war on Germany. On the 17th, Russia invaded Poland. Warsaw capitulated on the 27th.

Just over a year later (7 Sep 1940), the German Luftwaffe began its Blitz bombing campaign against London.

Autumnal Equinox - 22 September 2016

The 2016 September equinox comes on 22 September, at 3:44 p.m. CDT (20:44 UTC). In the Northern Hemisphere, the sun is rising later now, and nightfall comes sooner. This is our autumn equinox, when the days are getting shorter in the Northern Hemisphere. At this equinox, day and night are approximately equal in length. For us in the Northern Hemisphere, people are enjoying the cooler days of autumn even as preparations for winter are underway. South of the equator, spring begins.

The term equinox can also be used in a broader sense, meaning the date when such a passage happens. The name "equinox" is derived from the Latin aequus (equal) and nox (night), because around the equinox, the night and day have approximately equal length.
